Abstract

The invention belongs to the technical field of effective plant component extraction and particularly relates to a high-extraction-rate preparation method for curcumin. The method comprises the following steps that 1, absolute ethyl alcohol, inorganic salt, absolute methanol and distilled water are sufficiently mixed to form an extraction reaction solution; 2, curcuma powder is added to the extraction reaction solution, a low-temperature ultrasonic reaction is conducted for 30-60 minutes, a micro-current reaction is conducted for 20-50 minutes, and a release solution is obtained; 3, the release solution is put into a reaction kettle for gradient ultrasounding for 3-5 hours, and an extraction solution is obtained; 4, the extraction solution is subjected to constant-temperature centrifugation and then filtered, and a crude curcumin extraction solution is obtained, eluted and concentrated to obtain curcumin. According to the method, the problem is solved that the extraction amount is lowin an existing extraction method, through cooperation of microcurrent and ultrasound, the cell breaking rate is increased, and the extraction rate of the curcumin is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of extraction of effective plant components, and in particular relates to a method for preparing curcumin with high extraction rate. Background technique [0002] Curcumin, the chemical name is: 1,7-bis(4-hydroxy-3-methoxybenzene)-1,6-heptadienedione, the structural formula is shown in formula 1, and it is a rare diketone in the plant kingdom. The active ingredient can be extracted from some plant rhizomes in Zingiberaceae and Araceae. Curcumin is an orange-yellow crystalline powder with a slightly bitter taste and insoluble in water. It is a food additive with high safety. Its function and status are incomparable to any natural plant pigment. It is mainly used in food production for candy, Coloring of beverages, cakes, cold drinks and other foods, especially for protein coloring. In terms of medical applications, curcumin has anti-oxidation, anti-cancer, anti-inflammatory, elimination of free radicals, an...
